| Tartalmi kivonat: | In this paper authors present the preliminary results of the geochemical-petrological study of the granitoid rocks (Dienbiemphu- an a Queson-complex) in Vietnam. Several petrochemical diagrams and parameters have been used to recognize the nature and the tectonic affinity of these intrusive rock assemblages. Majority of them show calc-alkaline character, however, the evolved formations display higher alkaline-content. Both granitoids are characterized by a transitional affinity, they show both compressional and extensional features as well as S- and I-type nature. The plutonic rocks of these two complexes exhibit similar penological and geochemical characters indicating that they were formed in the same tectonic position: in the inner part of the continental margin. |
